Answer 1

Answer:

Question:-

Which of the following instruments are provided on the exhaust line to reduce the pressure?

a. Ducts

b. Muffler

c. Strainers

d. Purifiers

Answer:-

The correct option is Muffler.

Explanation:

• The exhaust fumes from internal combustion engines are channeled via mufflers, often referred to as silencers, to reduce their loud emissions.
• To be successful as a sound reduction device, a muffler must reduce the exhaust gas velocity and either absorb sound waves or cancel them by interfering with reflected waves coming from the same source.
• The primary sound-absorbing material used in mufflers is a thick coating of tiny fibers; sound waves cause the fibers to vibrate, converting the sound energy to heat.
• Sound waves are attenuated by reactive mufflers, which interfere with them.
• Thus, annular chambers that are typically filled with a sound-absorbing material are connected to a single tube through a few small holes to form straight-through mufflers.
